The 721-foot bridge takes cyclists over the city’s harbor instead of around it. Nice. The notoriously bike-friendly city has more than 221 miles of bike lanes — including many that are protected from traffic — and the city says that 52 percent of workers or students commute by bike each day.

The idea is to power trucks with electricity, which means no tailpipe emissions from the trucks (although possible emissions from trucks, depending on how the electricity was generated). A one-mile test system will be built next year to be used by four test trucks outfitted with pantographs and alternative power sources when not running under wires. Very interesting and not as pie-in-the-sky as it sounds, given that cities such as San Francisco still use overhead wires to supply electricity to many buses. In fact, such a system has been looked at as part of Metro’s ongoing 710 Corridor studies.

As other agencies have found, railroad cars are proving to be a harsh setting for wi-fi equipment coupled with high demand that consumes the wi-fi that is available. Wi-fi is proving somewhat reliable for things such as email, but not big tasks such as watching video and uploading and downloading big files.
